Having P2262 and P2099 codes, and when I bench the diverter valve with 12v battery, the valve will energize and retract which seems normal.
But when it is mounted to the turbo.
1. While looking for the ground wire. I found both wires are grounded to the chassis, but not to battery negative terminal 2. With engine running. one of the wire is producing 13v+ with chassis ground but valve is not energized. 3. inserting the multi-meter positive probes to either connector, and negative to battery. revving the engine will not bring up enough voltage to energize the valve. only shows 0.02v +-.
is there a electrical short somewhere? or I am doing the whole test wrong?
